I've got a 1970 Dart with a LRT frontend, that uses the torsion bars, and has rack and pinion steering. CalTracs and split mono leafs in the rear. True 10.5 tires. Trying to get the suspension under control, it's either on the bumper or spinning, but it's getting closer. In Denver, 7700 ft DA or so, 8.90's @ 155.
